well mine is with the latest firmware or maybe i just need long nails, but i seem to constantly have to hit the buttons over and over again mainly to go back, also the web seems to freeze for a few seconds before it responds to taps, i also notice playing music thru my bh-503 stereo headset it seems to skip or stutter every now and then, nothing like the n85 when i use it for music thru the bh-503, i only had it 2 days so its not fair to judge it so quickly, i do like the size of the screen and the resolution for movie watching and videos of it, and music thru the wired headset is nice but i definitely prefer the n85 at this point so far, also battery lifer on the n85 is much better so far.
Has anyone had an issue with there stereo bluetooth headsets with sporadic interferences.
